Extremely pleased with the results of INTERPROBE’s work for years.

INTERPROBE is a stealthy surveillance team with great support personnel. They have delivered excellent surveillance service on sensitive domestic and international matters on numerous occasions.

After more than 50 years of heading one of the first and most recognized P.I. Firms in the Washington, D.C. Metro area, without reservation I can say that INTERPROBE was our first choice for contract surveillance and technical investigative services…

My go-to investigators for more than 15 years; prior to receiving my judgeship.

They made a case against my client and I decided I better get them on my side for the future. I have used them ever since.

…Ultimately, all of our cases requiring surveillance or a technical touch were referred to them. We depended on their capabilities and appreciated their reliability and fairness for more than 20 years.

Great results by these investigators. They are accurate, ethical, and very persuasive in court.

I consider INTERPROBE my east coast ‘office.’ They have been an asset for surveillance and technical countermeasures for our firm for more than 15 years. Their support on cross-national cases and assignments unique to the Washington, DC area is highly valued.
